reloading the 300Blk

[SkaerE]

do i need 300 blk dies or can i get by with 300 whispers... fireball... or similar?

seems only 1 company makes dies named 300 blk and they are pretty pricey.

FWIW i have a rcbs rockchucker and dillon 550b. do i just need a 3 die set or something else for the 300?

I believe the difference in Blackout, Whisper, 300-221 is about the same as 223 and 5.56

Forster, Redding, Lee, and Hornady make dies marked 300 BLK.

Redding told me today that they do in fact have 300 AAC BLACKOUT dies in stock and your dealer can order them.

I'm using my old .300 whisper dies for my new .300 BLK barrel and haven't noticed any problems yet.
